Soil Summary:

dominant soils are shallow to moderately deep to bedrock, very flaggy sandy loam and flaggy loam surfaces over clays and very channery and flaggy sandy loams, no lime present, weak to strong development; unit dominated by Pima County soil survey map units 75 (Spudrock-Boriana complex, 10 to 35 percent slopes) and 77 (Spudrock-Lemmon complex, 15 to 45 percent slopes). These units comprise 68% and 29% of the ELT, respectively

Geologic Materials:

alluvium, colluvium and residuum associated with the Catalina-Rincon igneous metamorphic complex (TXm) comprises 100% of the unit

Landforms:

moderately to finely dissected, moderately to deeply incised mountain slopes (ridge lacks dissection)

Land Type Association: LTA 13
